    You can't go back; the database format version number is there precisely to
    mark incompatible changes.  I recommend that you try to figure out why p5 is
    losing for you.  For example, take a backup copy of your database dumped by p2
    and run it in side-by-side comparison on both p2 and p5.  If you can measure a
    difference in this kind of a single-variable test, then the trick is to try to
    figure out what part of the system is causing the problem, usually by
    eliminating one background task from each system over and again until the
    difference goes away.

    Good luck,
